This is not necessary any longer since the changes of 1b76ff4887
(Disable wxWebRequest tests on CI platforms without Python 3,
2021-05-16) as we require Python 3 for httpbin anyhow.
This currently means macOS 10.11 only, which is only used on Travis CI
and Python 2 installation there is broken anyhow, so this doesn't make
anything worse than it already is.
Python package hosting seems to randomly decide which version of the
package to return to pip running under Trusty: in addition to werkzeug
(see last commit), the version of flask has spontaneously changed from
1.0 to 1.2 in the latest build too.
Just hardcode the versions of all dependencies in the last successful
build and hope they keep working for longer than a day.
Crazily, pip installs seem to be non-deterministic as installing httpbin
in https://travis-ci.org/github/wxWidgets/wxWidgets/jobs/765946720
pulled in werkzeug 0.16.1 which works with Python 3.4, but doing it
again tries to use werkzeug 1.x which isn't.
Fix the version explicitly to work around this.
Trying to use Python 2 under Trusty is hopeless, as pythonhosted.org has
already started dropping support for non-SNI clients and will drop it
completely soon, see https://status.python.org/incidents/hzmjhqsdjqgb
and https://github.com/pypa/pypi-support/issues/978, and SNI is not
available in the system Python 2 version (2.7.6, which is less than
2.7.9 in which it was added).
Note that we still can't use Python 3 everywhere as long as we have
macOS 11 builds as it's not available there.
Amazingly, updating a package has no problems with installing a newer
version incompatible with the current Python version, such as installing
pip 21 when using Python 3.5.
Somehow installing decorator==4.4.2 worked a few times, but then stopped
and now fails with
Could not find a version that satisfies the requirement
decorator==4.4.2 (from versions: )
No matching distribution found for decorator==4.4.2
Try using explicit URL.
There just doesn't seem to be any way to make this work right now, so
handle dbgsym packages installation failure and disable leak detection
in this case.
Hopefully ddebs.ubuntu.com repository will be updated in the future,
allowing this to work again.
Add -dbgsym packages to extra_deps and pass them to the same apt-get
command we use for installing all the other dependencies.
This is slightly faster and also makes it simpler to pass extra options
to apt-get, as we're going to do in the next commit.
Using docker results in errors due to rate limit on pulling, so try to
reduce its use as much as possible. It still has to be used under Ubuntu
14.04 because it has a version of Python too old to work with HTTPS
servers using SNI and so using pip fails there.
Simplify things by putting setup.h files themselves under version
control and getting rid of setup0.h ones.
The initial motivation for using separate setup0.h files was to allow
having local changes to setup.h, but with Git there is a simple way to
do it by using "git update-index --skip-worktree include/wx/msw/setup.h"
for example, so we don't really need setup0.h any more and dropping them
makes things simpler.
